Description
Analog Power Supply.
Differential Data Input, Positive Port, 50 Ω On-Chip Termination.
Differential Data Input, Negative Port, 50 Ω On-Chip Termination.
Analog Ground.
LOS Threshold Adjust Resistor.
With one 100 kΩ on-chip, pull-up resistor, BW_SEL = 0 for 1×/2× FC, BW_SEL = 1 for 4× FC.
With one 100 kΩ on-chip, pull-down resistor, LOS_INV = 1 inverts the LOS output
to be active low for SFF.
LOS Detector Output, Open Collector.
Output Buffer Ground.
Differential Data Output, CML, Negative Port, 50 Ω, On-Chip Termination.
Differential Data Output, CML, Positive Port, 50 Ω, On-Chip Termination.
Output Buffer Power Supply.
Disable Outputs, 100 kΩ On-Chip, Pull-Down Resistor.
Average Current Output.
Power Input for RSSI Measurement.
Photodiode Bias Voltage.
Connect to Ground.
1 P = power; DI = digital input; DO = digital output; AI = analog input; and AO = analog output.
